Copernicus ROSE-L SAR Mission

Inhalt:
This paper provides an overview of the Copernicus L-band SAR mission referred to as ROSE-L (Radar Observation System for Europe at L-band), which ESA has started to implement (currently in Phase B2). In particular, we discuss the ROSE-L system and instrument design focusing on the envisaged SAR modes and their key performance parameters, and critical novel technology developments. Furthermore, we outline the approach for the implementation of the split-spectrum technique at SAR instrument level, which is required for the Ionosphere phase correction to ensure high-quality SAR interferometry data.
